Hi, I have XnView Classic newly installed under Windows 10 Prof. I used to be able to see all my cdr files as thumbnails if I entered the corresponding directory. Now that does not work any more. When I click on a thumbnail, the answer is (in German, I translate): "cant open file. Go to settings, click on open all available formats". I do that but that does not work".
Solutions??

sorry for necroing this thread, but I have the same problem. I verified the settings mentioned (couldn't find the .ini file because its XNViewMP perhaps), in About->Formats cdr is visible though, still I get no preview
